An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-6953 in the wild and no public exploit code.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2018-6953/ (Markdown: https://insights.sbomify.com/CVE-2018-6953/index.md)","id":"CVE-2018-6953","markdown":"https://insights.sbomify.com/CVE-2018-6953/index.md","name":"CVE-2018-6953","record":{"aliases":["GHSA-mcc7-qxrw-m8m8"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CCN-lite networking library","requires_auth":"none","summary":"A buffer overflow in the NDNTLV parser allows attackers to cause out-of-bounds memory access, potentially leading to code execution or crashes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ccn-lite","vendor":"ccn-lite"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"In CCN-lite 2, the Parser of NDNTLV does not verify whether a certain component's length field matches the actual component length, which has a resultant buffer overflow and out-of-bounds memory accesses.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Memory corruption in n/a","id":"CVE-2018-6953","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in n/a","id":"CVE-2018-6954"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2018-6952"},"products":["n/a"],"published":"2018-02-13","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2018-12889","kev_date_added":null,"published":"2018-06-26"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2018-7039","kev_date_added":null,"published":"2018-02-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2018-6948","kev_date_added":null,"published":"2018-02-13"},{"cvss_score":9.8,"headline":"Multiple integer overflows in CCN-lite before 2.00 allow context-dependent attackers to have unspecified impact via vectors involving the (1","id":"CVE-2017-12465","kev_date_added":null,"published":"2018-02-07"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-12466","kev_date_added":null,"published":"2018-02-07"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-12468","kev_date_added":null,"published":"2018-02-07"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["n/a"]},"summary":"A buffer overflow in the NDNTLV parser allows attackers to cause out-of-bounds memory access, potentially leading to code execution or crashes.","url":"https://insights.sbomify.com/CVE-2018-6953/"}
